Effect of Storage Times on Sperm Function, Sperm Chromatin Structure Assay (SCSA) and Correlations Between Fertility and SCSA in Boars

摘要

This study was designed to evaluate the changes in sperm motility, viability, HOST(hypo-osmotic swelling test), IVP(in vitro penetration), SCSA(sperm chromatin structure assay) during storage of liquid semen collected from boars with different farrowing rates using AI, and to find the relationship between boar fertility through AI and sperm diagnostic parameters during semen storage. The results of HOST were significantly decreased according to the increasing of in semen storage days and the resultsof IVP were significantly decreased at 3 days of semen storage (P<0.05). The %Red was significantly different among the >80%, 70-80% and < 70% farrowing rate group at semen storage day 6(P<0.05). The correlation coefficients between the %Red and farrowing rate were increased according to the semen storage. In conclusion, these results suggest that the sperm parameters evaluated in these studies may be useful indicators to predict the fertility of AI and evaluate the semen quality in boars.
